I got an 8 year old cat from a rescue centre and took ages teaching her to use the cat flap. Then she got attacked by a large Tom and now won't go out. How can I boost her confidence?
You can't boost her confidence. If she is a timid girl, and this tomcat bullies her, nothing will make her want to run the gauntlet of his aggression. why not let her stay indoors, where she is happy and safe?
